DRAFT ATTACHMENT FOR COOK-STOVES.

Specification of Letters Patent.

Patented April 17, 1906.

Application filed May 22,1905. Serial No. 261,628.

To all whom it may concern:

Be it known that I, JOHN EMIL THORELIUS,

Iron Mountain, in the county of Dickenson and State of Michigan, haveinvented certain new Improvements in Draft Attachments for Cook-Stoves,of which the following is a specification.

This invention is intended to be applied to cook-stoves of the varietyemploying upwardly-projecting hoods for warming purposes; and the objectof the invention is to provide an adjustable attachment adapted tocreate a draft or suction up through the hood and into the flue for thepurpose of withdrawing smoke, steam, and objectionable odors generatedduring the cooking operation and which under ordinary circumstances aredissipated through the house.

The invention further relates to the means for adjusting such attachmentto open and close communication with the flue and to so arrange theparts that the attachment may be fitted to stoves of the ordiary varietywithout materially altering the construction of stoves, therebyincreasing the field of use fulness of the invention.

The invention consists in the features of construction and combinationof parts hereinafter described and claimed.

In the drawings, Figure 1 is a front elevation of a cook-stove havingthe device of the present invention; Fig. 2, an end elevation showingthe draft-hood extended Fig. 3, a sectional view of the draft-hoodextended, and Fig. 4 a similar view showing the drafthood closed.

The device of the present invention is applied to a cooking-range 1having a top 2, an oven-door 3, and upper and lower doors 4 and 5,respectively. The cooking-stove is provided with an upright hood havingcurved end walls 6, terminating at their upper ends in an overhangingstraight portion 7, which forms a support for a top 8 and a ledge orshelf 9, adapted for the reception of food which it is desirable to keepWarm. The stove is provided with a flue 10, which passes through theshelf 9 and top 8 of the hood and leads to any suitable point for theescape of the products of combustion. The hood is provided at one sideof the flue with a cross-wall 11, having therein a port or passage 12,leading into the flue, which latter is preferably squared at the point13, which abuts agalnst the cross-wall to allow of a firm and tightjoint at the point of communication through the opening 12 with theflue. The cross-wall 11, in combination with the adjoining end wall,forms a rectangular draftchamber, and the shelf or ledge 9 at this pointis provided with a recess 14 in its forward edge, so that the openingfrom the rectangular draft-chamber to the top of the stove ispractically unobstructed. The draft-chamber serves as a casing for adraft-regulator 15, consisting of an inner section 16, open at both endsand at the bottom, and an outer or closing section 17, open at the innerend and at the bottom, but closed at its outer end by means of a plate18, provided with a handle 19 for regulating the position of thesections, which are adapted to telescope into one another. The innersection is provided at the lower edges of its side walls with guideways20, adapted to embrace the lower edges ofthe outer or closing section,and the outer section is provided with abutments 21, adapted to preventthe entire withdrawal of the outer section; but said lugs are sopositioned as to allow the sections to be telescoped to gether by themovement of the outer section.

The side walls of the inner section of the draft-regulator serve whenthe regulator is closed, as shown in Fig. 4, to cover the opening 12,leading to the flue 10 and serve the purpose of a damper; but in orderto provide for the further regulation of the opening 12 a slide-damper22 may be also provided for closing the escape-opening 12 at any time itmay be desirable.

In use when it is desirable to start a fire in the stove the sections ofthe draft-regulator are preferably closed, which closes the escape-fluefor the stove and allows the fire to be kindled Without difficulty andwithout the impairment of the stove-draft, but after the fire has becomethoroughly kindled and the cooking operation begun the sections of thedraft-regulator may be drawn out to any desired degree, thereby openingthe port or passage 12, which creates a supplemental draft from the topof the stove and tends to carry up the flue any smoke, steam, orobjectionable odors that may be occasioned by the cooking operation. Atthe same time the overhanging sections of the draft-regulator form anoutwardly-projecting hood which is positioned at a point to mosteffectively collect and carry away the smoke or vapors of the cooking,so that they will not be dissipated through the house and will notinterfere with the health and comfort of the inmates. The draftregulatoris preferably positioned on the side of the stove immediately above thefire-box, which is ordinarily the part of the stove most used forcooking; but the suction occasioned by the regulator will ordinarily bestrong enough to carry away smoke or vapors from any part of thestove-top, leaving the air pure and clean in the immediate vicinity ofthe stove.

It will be seen from the foregoing'descrip tion that the device of thepresent invention is simple in construction and arrangement and that itdoes not interfere to any appreciable extent with the operation of thestove and that it renders the cooking operation more pleasant andsatisfactory than would be the case if noxious odors and vapors weredissipated through the house, as is ordinarily the case.

What I regard as new, and desire to secure by Letters Patent, is

1. In combination with a cook-stove provided with a raised stationaryhood having a top and a ledge or shelf, a cross-wall between the top andledge or shelf forming a draftchamber and provided with an opening leading to the flue of the stove, and an extensible draft-regulator open atthe bottom and inner end and closed at the sides and outer end andadapted to be outwardly drawn from the draft-chamber to overhang thesurface of the stove to create a draft up through the extensibledraft-regulator and draft-chamber to the flue, substantially asdescribed.

2. In combination with a cook-stove provided with a raised stationaryhood having a top and a ledge or shelf, a cross-wall between the top andledge or shelf forming a draft chamber and provided with an openingleading to the flue of the stove, and a draft-regulator consisting of aninner section open at both ends and at the bottom, and an outer sectionopen at the bottom and inner end and closed at the outer end, thesections being adapted to telescope one into the other and adapted to bewithdrawn to overhang the surface of the stove and form an extensiblehood to create a draft through the draft-regulator and draft-chamber tothe flue, substantially as described.

3. In combination with a cook-stove provided with a fixed u right hoodhaving a top and a ledge or shel and having a flue-pipe passing throughthe top and through the ledge or shelf, a cross-wall abutting againstthe flue and extending from the top to the ledge or shelf and providedwith an opening leading to the flue and forming a draft-chamber, and adraft-regulator consisting of an inner section open at both ends and atthe bottom, and an outer section open at the bottom and inner end andclosed at the outer end, the sections being adapted to telescope oneinto the other and adapted to be withdrawn to overhang the surface ofthe stove and form an extensible hood to create a draft through thedraft-regulator and draft-chamber to the flue, substantially asdescribed.
